After installing it,it would appear like this in your browser -

2. After installing it download this script which runs with the help of this add on(greasemonkey) --

Install this script and make sure the monkey on the right side of your
mozilla screen is colored (which means greasemonkey is activated,to
activate or deactivate just click on it)

3. Now go to the site which tells you to do the survey and asks for your information etc..

4. You'll see an option on top left side of the page which says '' Press CTRL+SHIFT+F to fill in form. ''

Do as directed..press CTRL+SHIFT+F and you will see that the form gets
filled on its own and all the information filled out there is completely
random !

Click on submit and you are registered on the site and now you can easily download what you wanted to ! :)

This is all random stuff filled by the script.

BUT

5. Some sites may tell you to verify your identity by logging into your
mail and opening some url or to get some pin ! For this all you have to
so is go to yopmail.c0m/en/ . Go to this site and you'll get a
temporary email id for around 15-30min.>paste that temporary email id
at the place of email id which your intelligent form filler has
randomly filled>click on submit form.

6. Check yopmail.c0m/en/ Inbox for the mail from the site>Get the pin or confirmation link>you are done !

Here as you can see two mails from the site where we have to forcefully
register and the confirmation link plus password (other mails are just
spam,ignore them).

OR

7. Some sites may ask you for voice calls confirmation ..

In that case go to this site http://www.k7.net/ ..on this site you can receive voice calls via mail ! So you bypass Survey again without giving any details !
